Astros vs Padres MLB Betting Preview
We’ll start with Peter Lambert’s estimators, ranging from a 3.35 xERA to a 4.46 Bot ERA, both wide-ranging and above his 3.06 ERA.
As one would imagine, he’s been a strong contact manager, allowing just 6.5% Barrels/BBE with a 37.7 HardHit% behind a solid, but unspectacular 15 K-BB%.
However, after posting a 22 K% and 10.3 K-BB% through his first nine starts, Lambert has a 26 K% and 19.1 K-BB% in 10 starts since. Over his last six starts, he has been below a 20 K-BB% only once.
Lambert hasn’t changed his pitch mix or his velocity, but his pitch modeling has improved, most substantially on a changeup with a 58 Pitching Bot mark over those last six starts and a 111 Pitching+ as opposed to 44 and 72 in his first nine.
That may explain why LHBs sit below a .290 wOBA and xwOBA against him on the season, but the Padres will probably only send three to four LHBs out against him.
That’s only a small problem because while RHBs have a .328 wOBA against him, Statcast suggests they deserve a .283 xwOBA.
The San Diego offense has picked it up as of late with BARTOLO’s projected lineup averaging a 108 wRC+ vs RHP this year and 123 wRC+ over the last 30 days, but the former number includes Ty France at 139 and Luis Campusano at 162, which nobody probably expects them to sustain. Though we probably expect Fernando Tatis Jr. and Jackson Merrill to improve on their 104 and 84 marks, respectively.
Still, I have Lambert, whose ERA is nearly a half run better than Michael King’s, exactly a half run better than his opponent, whose underlying metrics run from a 4.19 FIP to a 4.58 xERA.
Over the last five seasons, King’s K-BB has declined from 25.1% to 22% to 19% to 16.2% to finally, 11.2% this year.
Allowing 6.6% Barrels/BBE over the first three of those seasons has turned into 9.6% in the last two. A sinker and four-seam fastball averaging at least 94 mph in the first two of those seasons haven’t averaged 93 mph in any of the last three.
Then, as good as the projected Padres’ lineup average 123 wRC+ over the last 30 days is, that's matched by the Astros' 123 wRC+ against RHP and over the last 30 days too. They also average a 20-point higher road/home wRC+ than San Diego’s projected nine.
That’s two distinct, sizeable advantages for the road team, and where the Padres gain some back defensively and by playing in San Diego, I still make the Astros small favorites here.
I’m quite happy that I’m showing the larger edge over the first five innings because I have no qualms about avoiding the potential appearance of Mason Miller.
This is easily our smallest edge so far, though, so I’d only endorse it to -105.
Picks: Astros (F5) +100, 0.5u | Bet to -105
